GARLINE.

Toy all wkontt may concern: l 'Y v v'Be it known ,that I, ROYC. MUNRO, a citizen of the United States residing in Chif cago', in the countyof/ook and StateV of Illinois,*have invented anew and useful 11nprovement'in Carlines, of which the Vfollowis'a specication. i i

in Y v he invention relates to carlinesinore particularly `designed'for use in freightcar roof frames ,and has for its objects tosiinplify theconstruction of. the carline andattain 1 economiesrin manufacture, at the sa-Ine time producingvacarlineof great strength and'v stiffness against vertical and Atorsional strainsf f ,y y

With suchobjects in view, aswell as other advantages .which maybe incidentto the use Y.of ythe improvements, the invention consists in the parts and combinations thereof hereinafter set` fortha and claimed, withv the understanding that` the several necessary elements constituting ,the saine maybe varied inproportions and arrangement without departing .from the'pnature and scope vof thel invention., Y, p .Y i

Y In order to make. theinvention more clearly understood.therev are. shown in thev accompanying drawings `means for-carrying the same into practical-effect, without limitingthe improvements, intheir useful appli# cations, to the particular constructions which, for Vthe purpose Aof explanation, have been .made the subjectof illustration. In the said drawings y Figure llis a plany View of. a portion of a car roof frame suitable for freight cars and other purposes, comprising a .carline ein.-`

vention being illustrated Ain a freight car structure.

The carline A is constructed of three steel' L-b-ars 8, 9 and 'l0' riveted together at theI apex of the carline and ridge of the roof,

and declining ythence to both of the side plates, and inclining away .frorneach other,`

longitudinally of the caron opposite .diagonals Vs0 as to form four widely separated points of attachment to the-side plates. Said bars are formedV and arranged so as to have horizontal top `flanges.' a and vertical side'- langes Z2. Y.

i The bar 8 is a main through bar spanning the roof from side plateto side plate ina diagonal direction, and at each end said flanges a and "bV are spl-it apart, the vertical and 4f) which are bentparallel with and. braced against the inneryfaces of the side plates,

and thev horizontal flanges extending across Y 4 and bearing on the tops `of the sidefplates and terminating in downwardly bent'hoolsv v v -12 which engage the outer faces of the side plates. 'The middle part ofi vthe'bar-8 is formed at theapeXv ofthe carline, with a short horizontal portion 13 whichcarries the ridge pole 3, and preferably the ends of the bar-are bentl upward relative to the main inclined portions to formv partslllv which' extend horizontally outward to and engage the sidesplatesas already described.

4The bars 9v and l() are supplementary -to the; bar 8-to form a: double-Y or ldouble branched carline, and are orinaybe coun-v terp'arts of each otherin size andforrnation, whereby their'preliininary. shaping is a siInple matter by a ysingle set of forming devices. Relative co-theiry outer inclined parts the inner ends 15 ofsaid supplementarybarsV are both bent to the left (as viewed' in ,i Fig..v1):tobring thern into parallelism-with;

themain bar 8, and arealso bent downward so as t0 be horizontal and-parallel with said portion 13 of theY main bar, YBeing thusl shaped the supplementary bars are arranged with their ends 41.5 at either side `of the verticalflan'ge Afb ofwsaid Amiddle partl, the

three vertical flanges thusy brought together being securely united by rivets or bolts 16./

away from the main bar on corresponding y and opposite diagonale, and theirr ends are One of said supplementary bars, as the bar 9, may be arranged with the top flange a of its end 15 flush with the similarflange of the bar 8 to form a further bearing for the ridge pole, and receive the securing bolt 19 of the latter. yThelflange a of the end 15 of the bar 10 is arranged under and in supporting contact with the under side Voi"v the flange a of said main bar (Fig. 2) The..

outer parts of the bars 9 and 10 are inclined formed for engagement with the side plates asillustrated and as already described with respect tothe .ends of the bar 8, and said ends 'are-secured by bolts 17 f which pass through their feet 11 and-through the side plates.

' The purlins are secured by bolts 18 which pass through the flanges a of the inclinedv 1 carline is strongly reinforcedso as to form f with horizontal top flanges and depending sidev flanges, and having a horizontal central apex, declining thence to the side plates and Y a solid point of resistance to receive the thrusts of thecarline branches; and that the carline as a whole is well adapted to durably resist all vertical, horizontal andtorsional strains arisingfrom'hard usageof the car.V

2. In akcarline for car roofs and the like, the combination of a main L-bar arranged having its ends formed for engagement with the side plates; and supplementary L-bars, having laterally bent innerV ends arranged at the sides of said apex with the vertical flanges of all of said kbars in contact and secured together to form a frame-supporting apex oftriplezwidth, and declining thence,
